Florida Rental Laws and Cold Weather: Is Your Property Compliant?

February 23, 2026 Nation Green Homes

Miami is known for its warm climate almost year-round. That's why, when unexpected cold fronts arrive and temperatures drop lower than usual, many homes reveal a problem that often goes unnoticed: they aren't prepared to retain heat efficiently.

And although extreme cold is not frequent, Florida recently recorded historically low temperatures, the coldest in some areas since 1909.
This led many homeowners to ask themselves an important question:

Is my home truly prepared for all kinds of conditions?

When a property is not properly sealed, cold air enters easily and heat escapes quickly. The result is usually:

• Increased use of the HVAC system
• Higher electricity bills
• Sudden temperature changes inside the home
• Greater wear and tear on the equipment
• Possible tenant complaints

In the case of rental properties, the situation goes beyond comfort.

In Florida, the law requires rental properties to meet basic habitability standards and that any existing heating system be maintained in proper working condition. Although state legislation does not explicitly require installing central heating in all cases, the property owner is responsible for keeping the property in safe and structurally adequate condition.

And this is where many property owners are surprised: a home may technically comply with the law… yet still lose heat if it is not properly protected.

The problem is not always the heating system

When cold fronts arrive, many people immediately think about the heating system. But in reality, the issue is often in the structure.

If the windows are years old or do not seal properly, cold air constantly enters. Or if the roof has leaks, worn materials, or poor installation, it allows warm air to escape and affects thermal insulation.
Talking about heating is not just about the equipment. It is about the overall performance of the property.

Impact windows are not only designed for hurricanes. They also:

• Create a better airtight seal
• Reduce the entry of cold air
• Maintain a more stable indoor temperature
• Improve energy efficiency
• Reduce outside noise

A home with properly installed windows retains heat better in winter and keeps cool air inside in summer. It is a solution that works year-round.

On the other hand, the roof is one of the most important elements when we talk about thermal stability. A roof in good condition and properly installed: improves insulation, reduces air leaks, decreases the load on the HVAC system, and increases the value of the property.
In a variable climate like Florida’s, an efficient roof makes a difference both in summer and during unexpected cold waves.

Additionally, not all HVAC systems perform the same during lower temperatures. In many properties, especially those with older units, the heating function becomes less efficient over time.
An aging system not only takes longer to cool or heat the space, but it can also consume up to twice as much energy compared to a newer, energy-efficient unit. This impacts indoor comfort and translates into significantly higher electricity bills, along with increased wear and tear on the system.

Meeting the minimum or protecting your investment

For property owners and investors, the goal should not simply be to meet the minimum legal standard, since a property in the best condition offers greater comfort for residents or tenants, lower long-term maintenance costs, and higher market value.
In a competitive market like Miami, efficient and well-protected properties generate greater trust and long-term stability.

If during the last cold wave you felt that your home lost heat too quickly, or if you received comments from tenants about thermal discomfort, it may be time to evaluate it.
